No additional fuel is required after the central flue is opcned,-no. matter howmany lines there may he in the kiln,because the intense heat which now pervades all parts of the kiln, except in that part which is under that central flue, being deflected and thrown into the center of the kiln, will, in an incredibly short space of time, complete the burning without additional fuel.

In order to prevent the cracking of the bricks from too sudden a cooling and contraction after the burning is effected, it will be necessary to keep the covers. on all the flues for a few days, and then to remove them' gradually, or meat a time, by slipping them sidewise off the top of the fines-.

I have found also that every brick in the kiln is burned to precisely the same degree of hardness, which, it is well known, is nev'er the The bricks over the arches 7 being filled with' fucl, tho

Either coal or wood may be used aim], for the arches, being closed, and the air to support cornbustron entering underneath the same, and below the grates, there is always so powerful a draughtthat very inferior qualities of both coal andwood may be burned ill the most rapid manner.
